USB memory sticks. Loads of us have them, and quite right too. They are an ideal way to easily move data around. But did you know they can also be used to take your favourite software programs and even operating systems with you?

The Portable Apps website provides specially created versions of popular and useful programs  to go on your memory stick. Simply download them to your stick and you can take your favourite browser (as long as it’s Firefox) and settings to any computer. You can also carry with you useful tools like the Gimp graphics package, Open Office and various media players. See the full list of applications here.

Such tools are ideal for anyone who works from home or away from the office regularly. No matter where you may be working, just plug your memory stick in and be assured of your usual tools, favourites and settings. And best of all, they’re all free.
